I don't know everything that I read this year; I stopped tracking them properly in the summer. These are, in no particular order, the best of what I know that I read over the year:
The Astronaut Wives Club by Lily Koppel
Running Scared by Edward T. Welch
A Girl of the Limberlost by Gene Stratten-Porter
Peril and Peace (Volume 1 of History Lives) by Mindy and Brandon Withrow
God’s Tribesman: The Rochunga Pudaite Story by James and Marti Hefley
The Cricket in Times Square by George Selden
The Epistle to the Hebrews by Homer Kent
Digging Ditches by Helen Roseveare
Devoted by Tim Challies
In His Steps by Charles Sheldon
Missions by Andy Johnson
The Light Princess by George MacDonald
God and the Transgender Debate by Andrew T. Walker
Writing to Learn by William Zinsser
Side by Side by Edward T. Welch
Jesus Among Other Gods by Ravi Zacharias
The Land of the Blue Burqas by Kate McCord
The Orphan Queen by Ottilie von Wildermuth
The Story Telling God Jared C. Wilson
It's an odd little mix of biography, history, fiction (generally older fiction), and theology.
